The renal pelvis is the reservoir in the kidney that collects the urine.
The substance that collects in a renal papilla is urine.
The bladder holds the urine 
The urinary bladder collects urine from the kidneys and stores it until it is ready to be expelled from the body. When the bladder contracts, urine is pushed into the ureters, which transport the urine to the bladder.
The cavity within the kidney that collects urine is called the renal pelvis. From the renal pelvis, urine travels down the ureter to the bladder for storage and eventual excretion.
The funnel-shaped basin that collects urine from the collecting ducts is called the renal pelvis. It is located at the top of the ureter, where urine is collected before being transported to the bladder.
The part of the kidney that collects urine after it is produced is called the renal pelvis. It serves as a funnel for urine flowing from the collecting ducts and directs it into the ureter, which then transports the urine to the bladder for storage. The renal pelvis is located in the central part of the kidney and plays a crucial role in the urinary system.
